Alabina Dall, 1902 - type genus of the subfamily Alabininae, the type species of the genus Alabina is extinct[3]

Bittiinae Cossmann, 1906

Bandel (2006) recognized a family Bittiidae Cossmann, 1906 [which should then be named Diastomatidae Cossmann, 1894 on the grounds of priority] with five subfamilies Bittiinae Cossmann, 1906 (usually placed in Cerithiidae following Houbrick, 1993), Finellinae Thiele, 1931, Alabininae Dall, 1927, Dialinae Kay, 1979 and Diastomatinae Cossmann, 1894.
This contradicts Ponder (1994) who grouped Finella with ScaliolaA. Adams, 1860 in a separate family Scaliolidae Jousseaume, 1912 [Scaliolidae is nevertheless kept distinct by Bandel (2006: 76) on the basis of having a shell agglutinating sand-grains]. It also contradicts Houbrick (1993) who holds the Bittiinae as a subfamily of the Cerithiidae.

It seems premature to reflect this scheme,[according to whom?] which upsets current usage, in the WoRMS classification until shell characters are cross-checked with at least another independent (e.g. molecular) set of characters.
